250ml Volumetric Flask, 3.3 Boro Glass, Class A, Ground Stopper, Karter Scientific 213W6 (Pack of 2)

Perfect for our lab.

This is a well made volumetric flask that accurately measures 10mL. Compared to purchasing at science supply shops, their price is reasonably good.

Came poorly packed but are very helpful in the home chemistry classes.

I have been teaching chemistry for 27 years. These volumetric flasks fit the bill for teaching students how to make diluted solutions! The flasks were perfect quality, arrived well-packaged and are perfect for my classroom needs.

i like the product, well packed, the price is right,

I weighed the volume of both flasks on a calibrated scale and both flasks were within their stated accuracy of +- 0.1 mL. The glass stoppers fit well and retain water within the flasks. Good deal.

This is my second Karter Scientifc Volumetric Flask that purchase; I also have a pair of 500 ml flasks. I am no scientist, I use them at home for various projects and they stand up well to casual home use. The glass seems very durable and it comes with a glass stopper that fits in the top of the beaker. I'm very happy with the product.

I love these little flasks! They arrived intact and I have used them for roughly 6 months now and they are very sturdy. Probably not the conventional use, but I use these to keep my salt and pepper in. They are so cute and a great conversation started for a Chemistry lover like myself.
